Noise properties of multi-combination information in x-ray grating-based phase-contrast imaging

Grating-based x-ray phase contrast imaging has attracted increasing interest in recent decades as multimodal and laboratory source usable method. Specific efforts have been focused on establishing a new extraction method to perform practical applications. In this manuscript, noise properties of multi-combination information of newly established information extraction method so-called angular signal radiography method are investigated to provide guidelines for targeted and specific applications. The results show that how multi-combination of images can be used in targeted practical applications to get a high-quality image in terms of signal-to-noise ratio. Our conclusions can be used for upcoming targeted practical applications such as biomedical imaging, non-destructive imaging, and materials science.
